One more note.
While I'm sure Chef Demetre is a great chef, He has a few of his facts mixed up.
First there is a lot of beef being sold in America's grocery stores that is better than commercial. Safeway even has a choice angus program.
I have been selling boxed beef for 25 years and the only thing I have aever seen labeled commercial is tenderloins for the low end steak houses.
Second The Distributers do not grade their own beef it is graded at the packing house, even if it is repacked it is never regraded.. This statement is pure bulls--t.
He is dead on about one thing though, wet aging is highly preferable to dry aging for a lot of reasons, less moisture loss, better flavor being the most important.
